Abstract

This paper presents a fully integrated, low
phase noise SiGe voltage-controlled oscillator with very
wide band for digital radio link applications. The VCO has
been fabricated using IBM 0.5µm SiGe5AM process. A
measured 38.5% tuning range around 5.2 GHz and a singlesideband phase noise varying between –100 and –96 dBc/Hz at 100kHz offset from carrier have been achieved. The
oscillator’s core draws 9 to 17mA from a 3V supply voltage.
